Q&A
As a Lewes homeowner, how do you handle common issues like duct leaks or an AC that won't cool on a hot day?
We understand how crucial a reliable AC is during our humid Sussex County summers. For duct leaks, which are common in older homes, our technicians perform thorough inspections to locate and seal leaks, restoring proper airflow and efficiency. If your air conditioner isn't cooling, we diagnose the root cause—whether it's a refrigerant issue, a faulty compressor, or a clogged system—and provide a clear, upfront repair plan. Our 24/7 emergency service means we're here to help restore your comfort quickly when you need it most.
What is involved in your HVAC maintenance service, and why is it important for my system?
Our preventative maintenance is a detailed check-up for your heating and cooling system. It includes cleaning critical components, checking refrigerant levels, inspecting electrical connections, and ensuring all parts are operating safely and efficiently. For families in our coastal climate, regular maintenance is key to preventing unexpected breakdowns during peak seasons, improving energy efficiency to manage utility costs, and extending the lifespan of your equipment. It's a proactive step to protect your comfort and investment.
We're considering a new HVAC system for our Lewes home. What does your installation process involve?
Our installation process begins with a free, in-home consultation. We'll assess your home's layout, insulation, and your family's comfort needs to recommend the right-sized system, including options from our American Standard and Mitsubishi Ductless lines. Our certified technicians handle the entire replacement with precision, from safely removing the old unit to installing and testing the new system for optimal performance. We ensure proper setup, clean up thoroughly, and walk you through operating your new system, all backed by our workmanship guarantee.
